Yes you can. Only pokemon that aren't allowed hidden ability would be pokemon that dont have their hidden ability available or if the sraft pool specifically said you had to use a specific ability (only applies to greninja and blaziken so wont matter to you)

Marmita none of your pokemon fall under that so you can use hidden abilities all you want on any pokemon
